MULTIPLEREGORDMAGAZINE PHONOGRAPH.

Application filed April 5, 1917. Serial No. 159,918.

To all whom it may concern.

Be it known that I, J osnrrr HUNTER Dron- INSON, a citizen of the. United States of America, and -a resident of Larchmont, lvestchester'c ounty, and State of New York, have invented certain new and useful-Imirovements in Multiple-Record-Magazine honographs, of which the following is av specification, reference being had to the accompanylng drawings, forming a part thereof.

' My invention relates-to improvements in multiple record magazine phonographs and its object is to provide an automatic mechanisrn for consecutively playing a plurality of records. More specifically, its object is to provide a simple and efficient automatic apparatus for removing'the upper one of several superimposed disc records after it has'been played and at the same time moving the reproducer back into position to engage the first part of the next adjacent record. w

In ordenthatfi'my invention may be thoroughlv understood, I will now proceedto describe the same in the following specification, and then point. out the .novel features thereof in appended claims.

Referring to' the drawings:

Figure 7 is a plan view of some of the parts shown in Figure 6, the view being taken on the line 7-7 of the latter figure.

Figure 8 is a side elevation of a part of the device, this figure showing in detail a lock actuating. mechanism. a

corresponding parts inall the figures.

1O designates a part of the case or frame of the instrument, 11 its reproducer, 12 its tone arm which is pivotally connected at 13 with a bend 14., which is swiveled at 15 and connected with the upper end of the am plifying horn 16.

17 is the horizontal table 'of the instrument and 18 is an inclined shelf at one side thereof.

Under the table is a plate 20 upon which certain parts of the apparatus are supported. 21 is the turn-table shaft, the lower end of which is supported by' a bracket 22 depending integrally from the plate 20. -A

worm gear 23' on this shaft meshes with a" worm 24 on ashaft driven by some suitable motor connected with a pulley 25 on the same shaft. The governor 26\,1s also on this shaft and carries a disc 27 which is arranged to coact with a manuallyadjustable brake shoe 28 in the usual manner. The upper end of the shaft forms a splndle 29 which extends freely through all but the upper one of a plurality Of'superimposed records 19.

30 is a vertically slidable sleeve mounted in a bearing 31 formed as a part of the plate 20 and supported upon the bifurcated end of a lever 32 which is affixed to a horizontal shaft 33 mounted in suitable bearings 34 under date-20. 35 is another lever affixed to shaft 33 to the lower end of which is attached a spring 36 which passes through an angle bracket 37 afiixed to plate 20. 38 is an adjusting member for the spring 36' by means of which its tension may be regulated.

The turn-table 40 fits over the spindle29 and is keyed to turn with the shaft but is 'at the same time free to move up vertically thereon. Theturn-table is supported on a disc 41 on the upper end of the sleeve 30; a disc 42 being under the turn-table and separated from the disc -11-by ball bearings 13.

It is desirable, as will appear later, to lock the sleeve 30 against its vertical movement during certain parts of the operation, and for this purpose I provide a screw 50 which passes through and engages threads in the upper part of bearing 31. A lever 51 is adjustably secured to this screw. A pin 52 near the lower end of this lever is in a slot in the end of a connecting rod 54. and a spring 55 aflixed to lever 51 and to connecting rod 51 at 56 has a tendency to seat pin 52' in the bottom of slot and to turn the lock screw 50 in the direction to lock.

At one corner of the plate 20 is a member 60 which forms bearings for a vertical post 61 capable of a rotary oscillation. 62 is a collar affixed to this post to hold it from moving downwardly. A lever 63 is affixed to its lower end. 61 is a bracket depending from plate 20 to support an adjustable stop screw 65 by means of which the inward movement of the lever 63 is limited. 66 is a spring which is arranged to oppose the outward movement of the lever 63 and the parts which are connected therewith, and has a tendency to hold the lever 63 against the stop screw 65.

70 is an arm which is-removably connected to the upper end of post 60. It has a vertical hub 71 through which a screw 72 passes into the post 61. this hub is made with a transverse slot which fits over a rib 67 on the upper end of the post so that the arm 70 will swing with the oscillations of the post. The free end of arm 70 is' constructed to form a head 73 in which is a rotatably supported member T-t having a central h1g7?) which, when the arm is in its inner position, determined by the adjustment of the stop screw 65. is in alignment with the spindle 29 and extends into the center hole of the upper record 19. The lug 75 and the spindle 29 are separated from each other at the plane between the upper two records 19. The lower end of the rotatable member is in the form of a small horizontal disc 76 from the center of which the lug 75 extends downwardly. This disc and the head 73 limit the upwazn movement of the records when they are raised by the spring 36.

On the motor driven turntable shaft 21 is a gear 80 which is in mesh with a larger gear 81 which is affixed to a vertical shaft 82. 83 is another gear on another shaft 81 on the lower end of which is a crank arm 83. This is connected by a rod 86 with lever 63 so that the rotation of gear 83 causes the post (31 to be oscillated and arm T0 to bc swung outwardly and back again. A slot and pin connection between crank 85 and The lower end of rod 86 provides a certain amount of lost motion and allows spring 66 to hold lever 3 against stop screw 65 during a part of the movement of the crank 85 over its dead center.

The gear 83 is spaced from and is higher than gear 81. Between them is a rock shaft 87. This carries a vertical transverse shaft to which are affixed a pinion 88 adapted to mesh with gear 81 and a pinion 8!) adapted to mesh with gear 83. is an arm extending from the rock shaft 87 and connected at its outer end with the core of a solenoid 91. 92 is a spring which raises this core and holds the pinions 8889 out of engagement with their respective gears. When, however, the solenoid is energized, the arm 90 is pulled down and the shaft rocked to bring the pinions 88 and 89 into mesh with the gears 81 and 83 respectively, so that the motor. driven gear 81 will, through this mechanism. drive gear 83 to swing the arm 70 outwardly and back again. As will be shown later, the circuit through solenoid 91 is broken automatically at the'desired time to release the gears 88 and 89 and allow the spring 66 to hold lever 63 against stop screw 65 and to thus hold the lug T5 in alignment with spindle 29.

At the other end of the rock shaft 87 is an arm 03 to which the lock actuating rod 51. is connected so that when the rock shaft 87 is actuated the lock screw 50 will be turned. This results in looking the sleeve 30 against vertical movement during the time the arm 70 is oscillating.

100 is a rigid arm affixed to the under side of the tone arm 12' This extends through a slot in table 17 and carries a sector 101 on its other end. 102 is another horizontal rock shaft from which an arm 103 extends to the core of a solenoid 104: by means of which it is actuated. A spring 105 overbalances the weight of this solenoid core. ()n the rock shaft 102 is a transverse shaft to the opposite ends of which are affixed friction rollers 106 and 107 which are respectively arranged to engage with the uppersurface of gear 81 and the under surface of sector 101 when the solenoid is energized. The movement imparted to rock shaft 102 by the solenoid is sufficient to cause the roller 10? to raise sector 101 and with it the tone arm 12 so that v the needle of the reproducer is raised from the record.- and the motor driven gear 81 will. through the friction rollers and the coacting parts. cause the tone arnr to be rc tr tcd frointhe end of the record to the beginning thereof. Then when the solenoid 10-! is deencrgizcd the spring 105 will cause the rock shaft 102 to turn to lower the sector 101 and the rcproducer until the needle of the latter engages the record groove.

1 will now describe the means for con trolling the encrgization of the solenoids. 110 is a circuit closer below the table 17, the

position of which is manually adjustable by means of a button above table 17. This is closed by engagement of the arm 100 with it as this arm is moved inwardlyby the record groove. When this circuit closer is closed a current passes from a battery or other source 111, through conductors 112 and 113 to and through solenoid 104 and back to the battery through conductor 115.

As soon as the solenoid 104 is energized a spring contact 116 which carries an armature 1 17 israised against an adjustable stationary contact 118. The spring contact 116 is connected by a Wire 119 with a circuit breaker 120 which, by wire 121, is connected with the battery .111. The stationary contact 118 is connected by wire 122 with. wire 113 which leads to. the solenoid 104. This results in the solenoid remaining energized even after the circuit closer 110 is openedas long as circuit breaker 120 remains closed.

The circuit breaker 120 will remain closed until arm 100 in its outward movement strikes it which will be at a time predetermined by the position of the circuit breaker 120. The position of 'this circuit breaker is adjusted manually by a button on the upper side of table 17 as will be described later.

110 is another circuit closer which closes a circuit from the batte. 111 through wires 112, 123 and 124 to and through solenoid 91, which circuit is completed through wires 125 and 115.

When solenoid 91 is energized it draws up a spring contact 126 against an adjustable stationary contact 127. The wire 112 from the battery 111 is connected to the spindle of gear 83 by wire 128 and a spring contact 129. Another spring contact 130 bears on the upper surface of this gear in certain of its positions. .131 is a wire from spring contact 130 to springcontact 126, and 132 is a wire from stationary contact 127 to the wire leading into the solenoid 91 so-that through these parts the circuit is maintained through the solenoid 9l to keep the gears which it controls in operation until the arm has been swung over with a record tq its outer position and back again. -A block of insulation 133 is set into gear 83 and at the proper time spring contact. 130 runs onto this insulation, thus breaking the circuit through solenoid 91and allowing spring 92 to move the pinions away from gears 81 and 83. The spring 66 will now hold the arm 70 to its inner position with its lug 7 5' in alignment with the spindle 29.

I will now describe the means for adj usting the positions of the circuit closers 110 and 110 and of the circuit breaker 120. Referring to Figures 1, 2, 10, 11 and 12, 140 is a plate spaced from the ,under side of table 17 and supported thereby. To this is secured a flat support 141. 142 is a pivot which rotatively supports an arm 143, the inner end of which is in' the form of a flat sector 144. The outer end of arm 143 is bent upward as at 145 and supports a block of insulation '146 on which is supported a pair of light springs 147'and 148. 149 is a contact electrically connected with the vertical part of arm 143. 150 is a contact on the spring 147 and 151 a. similar contact on sprin 148. The springs 147 and 148 have a tendency to hold the contacts 150 and 151 away from coi1tact149 a distance determined by the ends 152 and 153 of the springs which are bent over as shown and arranged to abut against. the back of the insulation block 146. i v

154 is a spring around pivot 142 and connected thereto andto arm 143 at 155 and so arranged as to have a tendency to swing arm 143 in an anti-clockwisedirection as viewed in Figure 1.

156 is a brake rod pivoted in bearings 157 on the plate 140. Its inn'errend is bent at right angles to form a brake finger 158 which is pressed against sector 144 by a comparatively strong spring 159 to hold the arm 143 against the action of spring 154. The other end 160 of rod 156 is bent at right angles in the opposite direction to thefinger 158 and to the outer end thereof is pivotally connected avertical rod 161 which passes up through table 17 and ter- Ininates in a. button 162.

The manner of setting this device is as .follows: The tone arm 12 is moved to such a. position that the reproducer needle is at the end of the playing part of the record and arm 100 is moved with the tone arm and positionedthereby. At this time the button 162 is depressed to move brake fin ger 158 oifxof' sector 144. The spring 154 will press springs 147 and 148 against the arm 100 with sufficient pressure to cause their contacts 150 and 151 to be moved against contact 149. Now button 162 is released and brake finger 158 pressing against sector 144 will lock the arm 143 in the position which it has assumed.

Whc 1' the. instrument is played. and the tone a m moved by the reproducer needle following the pitch of the spiral record groove until it has reached the position at which the parts have. been set as ('lescrihed,

the arm 100 will again close contacts 150 and 151 against contact 149 at the desired time. Contacts 150 and 149 form circuit closer 110, and contacts 151 and 149 form circuit closer 110". Thus when the reproducer needle reaches the end of the record, the solenoids -91 and 104 will be energized to perform their functions.

163 is another swinging arm supported on a pivot 164 on base 141. This is actuated by aspring 165 in a clockwise direction when released by pressing a button 166 downwardly. 167 is a block of insulation on the outer end of arm 163. A light spring 168 carried by this block has on its bent-over end 169 acontact 170 which is held by this spring against a contact 171 which is electrically connected with the arm 163. The position of this arm is similarly set when the reproducer needle is atthe beginning of a record. Contacts 170 and 171 form the circuit breaker 121) and are separated to deenergize solenoid 104 at the desired time.

The operation of the device may be seen trom'the foregoing description. but to make it clearer, I will describe it as a whole. A desired number of records are placed upon the turn-table 40 and the circuit closers 110,

in the manner which has been described and solenoids 104 and 91'energized.

I have shown that the energization of sole-' noid 104E caused the tone arm to be raised, brought back to the beginning of the records and lowered thereon. Also that at the same time the energization of solenoid 91 operates lock screw 50 and causes arm to be swung outwardly and back again. During this movement of arm 70 its lug engaging the upper record will cause the latter to be slid ofi' from the other records, the position of which will be maintained by spindle 29. V i 7 When arm 70 has reached its outer position, the record which it has carried with it, will drop and slide by gravity down the incline 18. As soon as arm 70 reaches its inner position and its alignment with spindle 29 maintained by spring 66 and stop screw 65, the spring contact 130 will .run onto insulation 133 to thereby break the circuit through solenoid 91. This then allows spring 92 to move rock shaft 87 to. disengage gears 88 and 89 from gears 81. and 83 and to release lock screw 50. The rotation of gear 83 will stop and the spring 36 will then raise the turn-table 40. This occurs before the tone arm has been wholly retracted, so that when the latter has moved out until arm 100 causes circuit breaker 120 to open the circuit through solenoid 104 to lower the reproducer needle, the latter will come on a new record. This operation will be repeated.

When it is desired to use this instrument with a single record, it is only necessary to remove the screw 7 2 and the arm 70.

Many structural modifications may. be made within the spirit and scope of this invention, and I intend no limitations other than those imposed by the appended claims.

In a phonograph, a rotary spindle, means for driving the spindle, a record holding turn-table slida-bly but non-rotatively mounted on the spindle,-a tone arm arranged to be moved in one direction to follow the radial pitch of a spiral record groove, an oscillatory arm having a head at its free end, a 'rotative member supported by said head havinga lug projecting downwardly therefrom adapted in the inner position of the arm to be in alignment with the spindle and to engage a record on the turn-table, means driven from said spindle for raising the tone arm and moving said tone arm in the opposite direction, other means driven from the spindle for moving said oscillatory arm across the turn-table to thereby remove the engaged record therefrom, means for'push ing said turn-table upward, said member being arranged to limit the upward movement of the turn-table by the engagement with a record thereon. and means actuated by the first aforesaid movement of the tone arm of a spiral record groove, an oscillatory arm i pivotally supported outside of the turntable, said armhaving a lug projecting downwardly adapted in the inner position of the arm to be inalignment with the spindle and to engage a" record on the turn-table,

shiftable gearing for connecting the oscilla-v tory arm with the spindle for swinging said arm in a' plane parallel with the'turn-table to thereby remove the engaged record therefrom, means for raising the tone arm and moving said tone arm in the opposite direc-' tion, electro-magnetic means for shifting said gearing into connecting position and for actuating said raising and moving tone arm means, and a circuit closer actuated by record groove, an oscillatory arm having a lug projecting downwardly adaptedin the inner position of the arm to be in alignment with the spindle and to engage a record on the turn-table,'a spring arranged to. hold said arm in its inner position, means driven from said spindle and controlled by the movement of the tone arm fonmovmg the tone arm in the opposite direction, and

othermeans' driven from said spindle and controlled by the movement of the tone arm for moving said oscillatory arm across the turntable against the action of said spring, to thereby remove the engaged record therefrom, and means actuated by the first afore s aid movement of the tone arm for controlling both of said spindle-driven means.

23. In aphonograph, a vertical rotary spindle, means for driving the spindle, a record holding-turntable mounted on the spindle, a tone arm arranged to be actuated intone direction to follow the radial pitch of a spiral record groove, a member rigidly aiiixed to said tone arm, an oscillatory arm pivotally supported outside of the turntable, said arm having a lug projecting downwardly adapted in the inner position of the tone arm to be in alignment with the spindle and to engage a record on the turntable, a spring adapted to hold-said oscillatory arm in its inner position, said arm being arranged to be swung in a plane parallel with said turn-table, to thereby remove the engaged record therefrom, a vertical shaft, connections between the vertical shaft and the oscillatory arm, a gear on the spindle, another gear on the vertical shaft offset vertically from said spindle gear, a rock shaft between said gears, a pair of pinions 'swingingly supported on the rock shaft and arranged to be movedinto and out of engagement with said gears by the movement of the rock shaft,'a solenoid having a core connected with and adapted to move the rock shaft, an, electric circuit therefor, a movable circuit closer in said circuit, manual means for adjusting the position of the circuit closer in theipath of movement of the tone arm member, a circuit breaker on one of said gears arranged-to break the circuit to the solenoid at a predetermined point in the movement of' the oscillatory arm, combined, with other means driven from said spindle for raising the tone arm and moving said tone arm in the opposite direc tion, and' electromagnetic means for con" trolling said raising and moving means for the tone arm.

24. In a phonograph. a rotary spindle. a turn-table thereon adapted to hold a plurality o1" dise reeords. an oscillatory arm having a lu e adapted in one position of the arm to be in alignment with said spindle but separated therefrom in the plane between the upper two reeords on the turntable. and means for moving said arm across the turn-table to thereby remove the upper record therefrom.

25. In a phonograph. a rotary spindle. a turn-table adapted to hold a plurality of disc records. an oseillatory arm. a freely rotative member supported by said arm. said member having a part adapted to contact with the surfaee of the uppermost record -on the turn table and a lu; depending from said part into said uppermost reeord. said lu; being adapted in one position of the arm to he in alignment with said spindle but separated therefrom in the plane between the upper two reeords thereon. means for raising the turn-table to bring the surfaee ot' theuppermost reeord thereon into eontaet with the aforesaid part of the rotative member. and means for moving said arm aeross the turn-table to thereby remove said uppermost reeord therefrom.

In witness whereof. I have hereunto set my hand this 4th day of April. 1917.
